MINERS PICK.

Application led March 23, 1927. Serial No. 177,665. y

This invention relates to new and useful improvements in ininers picks, and has for its primary object toiprovide a pick construction wherein the handle thereotl is of "i hollow metal construction and wherein highly novel, simple, and inexpensive means is provided for rigidly securing the pick head to the handle in such a manner as to prevent the turning of the head upon the han- U" dle and prevent the accidental disengagement of the same therefrom.

It is well known that the usual wooden.

handles of miners picks are readily breakable due to the striking of the same against the coal especially near the heads thereof,

frequently occasioning the loss of anentire day of one of the miners. Also the heads of picks now generally in use are ever liable to become detached from their handles which f1" is an ever present source of danger.

In carrying out the present invention there is provided Va hollow metallic handle and a pick head of generally conventional structure. said handle and said head being so formed as to permit of the rigid but yet de- 4H handle 5 of hollow metallic construction of predetermined length and diameter. vthe inner end thereof being of enlarged cross section as clearly disclosed atQ in the drawing.

The head 6 is of the double pointed type,

15 and is formed intermediate its ends with a shank 7 similar in cross sectional area and shape to the enlarged end 2 of the handle 5. Formed longitudinally through the shank 7 is a bore 8 threaded throughout substanml tiallv its entire length, the inner end of the bore 4 of the handle 5 being also threaded as to facilitate the attachment of the head to the `handle by reason of a threaded pin 3 threaded into the head bore and handle bore as clearly disclosed in the drawing. The head attacliing end 2 of the handle 5 at opposed points with respect to the bore 4 is forn'ied with threaded sockets 10-10 that open at the end of the handle. The head is also formed .in its shank portion 7 and at opposite sides of the bore 8 with bores 9 9 adapted for registration with the threaded sockets 10--10 in the handle 5 after which elongated bolts ll-ll threaded at their inner ends and headed at their outer ends are arranged through the bores 9 9 and threaded within the sockets 10-10 of the handle 5. As clearly disclosed in the drawing, the heads of the bolts are countersunk within the head of the pick so as to provide `a smooth surface at the outer side of the pick head.

It will thus be seen that I have provided a highly novel.7 simple, and inexpensive miners pick that is welladapted for all the purposes heretofore designated, and even though I have herein shown and described Y the invention as consisting of certain detail structural elements it is nevertheless to be understood that some changes may be made therein without affecting the spirit and scope of the appended claim.

Having thus described the inventiomwhat I claim is :m

In a mine1"spick of the class described, a tubular metallic handle having its head receiving end internally threaded, a pick head., a shank formed on the inner face `of said head for disposition against the inner end of the handle and having a bore extending therethrough in registrationwith the bore of the handle. said bore being also threaded, a threaded pin arranged within the adjacent ends of the bore of the handle and the bore of the shank for connecting the two together, an additional means for securing the head to the handle. said means comprising a pair of clonga ted bolts threaded attheir inner ends, said pick head and the shank being provided with through bores arranged on opposite sides of the main bore and 'through which the bolts extend, the inner of the handle being formed with threaded sockets on opposite sides of the bore, of the handle for receiving the inner threaded ends o f the bolts. 1

`In testimony whereof I affix my signature.
